Tuag casteting txheej txheem

Tuag casting yog txheej txheem hlau casting, lub hauv paus ntawm uas yog siv cov pwm los thov kev kub siab rau cov hlau molten kom nws tuaj yeem khov sai sai hauv pwm. Cov txheej txheem tuag casting feem ntau suav nrog cov kauj ruam hauv qab no:

Npaj theem: Ua ntej, cov khoom siv hlau yog melted thiab txhaj rau hauv kev tuag chamber ntawm lub cav tuag casting tuag. Lub tshuab tuag casting tuaj yeem ua tau txias chamber tuag casting tshuab lossis kub chamber tuag casting tshuab. Lub qub ncuav molten hlau rau hauv kev txhaj tshuaj chamber, thaum lub tom kawg coj cov hlau ncaj qha los ntawm insulated crucible.

Filling theem: Cov hlau molten sai ua rau pwm kab noj hniav los ntawm kev khiav thiab lub rooj vag ntawm pwm nyob rau hauv siab. Kev tsim ntawm lub rooj vag pab kom nrawm nrawm ntawm cov hlau thiab pab txhawb kev demolding tom ntej.

Solidification theem: Cov hlau txias thiab solidifies nyob rau hauv cov pwm los tsim cov yam xav tau casting. Kev tsim thiab tsim khoom zoo ntawm cov pwm ncaj qha cuam tshuam rau qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov casting.

Demolding theem: Tom qab casting solidifies, nws raug tshem tawm los ntawm qhib pwm. Cov txheej txheem no yuav tsum muaj kev tswj xyuas meej ntawm lub sijhawm thiab lub siab kom tsis txhob muaj kev puas tsuaj rau lub casting lossis hnav ntawm pwm.

Qhov zoo thiab qhov tsis zoo ntawm Tuag Casting:

Cov txiaj ntsig: Tuag castingsing qhov tseeb, siab saum npoo ua tiav, siab zog thiab hardness, thiab haum rau huab hwm coj ntau lawm. Vim yog kev txo qis ntawm kev siv tshuab, tus nqi hlau siv yog qhov siab thiab tus nqi tsim yog tsawg.
